Abstract (en)

The present invention relates to [1] a pigment water dispersion containing pigment-containing crosslinked polymer particles, in which a crosslinked polymer in the particles is a polymer that is crosslinked with a crosslinking agent represented by the general formula (1), and [2] a process for producing a pigment water dispersion containing pigment-containing crosslinked polymer particles, including the following steps (1) and (2): Step (1): subjecting a pigment mixture containing a pigment, a water-dispersible polymer and water to dispersion treatment, thereby obtaining an aqueous pigment dispersion solution containing pigment-containing polymer particles; and Step (2): mixing the aqueous pigment dispersion solution obtained in the step (1) and a crosslinking agent represented by the general formula (1) to react the water-dispersible polymer with the crosslinking agent, thereby obtaining a pigment water dispersion containing pigment-containing crosslinked polymer particles.
